Alexandre SIMON commented on IGNITE-3772:
-----------------------------------------

[~auszone] I even here have a limit of 2000 bytes with a PHP client.

 
{code:java}
<?php
$client = new Memcached();
$client->addServer("ignite1", 11211);
$client->setOption(Memcached::OPT_BINARY_PROTOCOL, true);

function storeAndAssert($key, $value) {
    global $client;

    echo "*** Test to store $key, len=".strlen($value)."***\n";

    if ($client->set($key, $value)) {
        echo "set return OK\n";

        if ($storedValue = $client->get($key) != $value) {
            echo "Server key value holding KO: ".$storedValue."\n";
        } else {
            echo "Server key value holding OK\n";
        }
    } else {
        echo "set return KO\n";
    }
}

function genValue($len) {
    return str_repeat('a', $len);
}

storeAndAssert('toto', 'val'.uniqid());
storeAndAssert('v1', genValue(100));
storeAndAssert('v1', genValue(500));
storeAndAssert('v1', genValue(1000));
storeAndAssert('v1', genValue(2000));
storeAndAssert('v1', genValue(1999));
{code}
Ouput :
{code:java}
*** Test to store toto, len=16***
set return OK
Server key value holding OK
*** Test to store v1, len=100***
set return OK
Server key value holding OK
*** Test to store v1, len=500***
set return OK
Server key value holding OK
*** Test to store v1, len=1000***
set return OK
Server key value holding OK
*** Test to store v1, len=2000***
set return OK
Server key value holding KO: 1
*** Test to store v1, len=1999***
set return OK
Server key value holding OK
{code}
As I suspect you would ask, PHP version is 7.2.21, libmemcached 1.0.18, pecl 
memcached 3.1.3.

But the more important thing is that with the same runtime and code client from 
a real memcached (1.5.16), everything is fine...

Any change this get resolved ?

 

Thanks.

> When a value which is larger than 32768 bytes is saved via Memcached client, 
> it ends up corrupted in cache. Most likely something wrong with the parsing 
> and the length of binary value is calculated incorrectly.
> Modified {{MemcacheRestExample}} which reproduces the issue is attached.
